wayland/output: Make each wl_output correspond to one monitor

Browse Source 
This is more in line with the protocol, and allows us to remove some
awkward code that tries to "combine" different metadata from different
monitors into one, which sometimes meant picking an arbitrary "main"
monitor, or "and" metadata together to find a common ground.
